Curiosity.

I think it may be because of the incredibly high prices of cell phone plans here, but unlike in the United States, where everyone always seems to be on their phones, I hardly see people here pick up their cell to make a call. In fact, when someone is on the phone, you can tell-- their voice travels all the way to the other side of the room, subway car, or bus-- and everyone turns and stares at them. (I don't think I've ever been stared at in the United States for speaking on a cell phone). It will be interesting to come back to the US and see how I feel about this...

(On the other hand, unlike in the US where people seem to multitask and do work wherever they have time-- the bus, the subway, the plane-- I hardly see people take their work on their commute. As vezes (sometimes) I would see UFRJ students read on the bus, but it was rare. Interesting, right?)
